Proview, the Chinese company that sued Apple over the iPad trademark, is on the receiving end of a lawsuit from its own lawyers.

The Grandall Law Firm is suing Proview for its 4 percent commission on Apple's $60 million settlement, about $2.5 million, according to a Sina Tech report.

Proview founder Yang Rongshan characterized Grandall's lawsuit as "nonsense," according to the report. He claimed that Proview is not currently under "normal operations" and should not be bound by the terms of its obligation to Grandall.
